Is there a KiCad symbol and footprint for the ESDA5V3L?
Yes. The symbol is Power_Protection:ESDA5V3L and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ESDA5V3L?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the ESDA5V3L datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the ESDA5V3L?
JLCPCB lists it as part C87911, with 9,751 in stock; the sellers' links on this page open their listings.
What can replace the ESDA5V3L?
Parts like it in the library: the MMBZ5V6AL by onsemi, the MMBZ5V6AL by Nexperia, the MMBZ5V6A by Shikues and the MMBZ5V6ALT1G by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the ESDA5V3L?
33 boards in 29 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
